Hi all,

Just installed v. 4.8.1 and created the doctypes needed for the sites structure. Now, when I'm publishing a node in the content tree, I get an ArgumentNullException:

Value cannot be null.
Parameter name: attribute

Stack Trace: 


[ArgumentNullException: Value cannot be null.

   System.Xml.Linq.XAttribute.op_Explicit(XAttribute attribute) +165046

   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +3707

The umbraco.config is empty (which makes sense since it never reaches the code in UpdateDocumentCache()) and I have checked that the node is indexed, which it is.

Anyone experienced this and got a hot-fix for it? :-) Got this odd feeling that I have missed something simple 'n easy. I've checked permissions and they seem to be just fine.

Thanks in advance!

All the best,

Bo
